 Sum, Difference and Double Angle Identities, Find the Error

In this activity, students are given worked out solutions to questions involving sum, difference and double angle identities. The worked out solutions have an error in them. Students must identify the error and provide a correct complete solution. I like that this activity allows students to think of this style of question in a scaffolded manner. The Mathematical Processes that are involved in this activity include using communication in order to learn and express understanding and develop mathematical reasoning.
